Description

Technical Field

[0001] This utility model relates to the field of dispensing technology, and more specifically, to a solvent dispenser for food testing. Background Technology

[0002] In existing technologies, solvent dispensers for food testing are a key piece of equipment, primarily used to accurately dispense the solvents required for testing into multiple sample vials to meet the high requirements for solvent volume, purity, and dispensing efficiency during experiments. However, some solvent dispensers currently on the market still have significant shortcomings in terms of structural design and ease of operation.

[0003] Common conveying methods such as slides, rollers, or belts lack precise positioning and buffering mechanisms, making the bottles prone to shaking, collisions, or even displacement during transport. This is especially true for lightweight sample bottles with small bottom contact areas, which are more likely to tilt or tip over, affecting the accuracy and safety of subsequent injection.

[0004] Existing injection components often employ threaded connections, nested plug-in connections, or snap-fit ​​assemblies. However, their designs do not adequately consider ease of operation and spatial layout, resulting in cumbersome installation and disassembly procedures. This is especially true in confined spaces or when components are located in hidden areas, requiring operators to use tools for assistance. This not only consumes time and effort but also increases the risk of damage to components due to operational errors. Furthermore, most existing equipment does not feature a modular design, and injection components are not assembled independently. This necessitates stopping the machine and disassembling multiple peripheral structures during maintenance or replacement, increasing downtime and impacting production or testing efficiency.

A sliding rod is slidably installed on the side support frame, and a movable clamping plate is installed at one end of the sliding rod. A compression spring rod is installed on the side support frame, and the compression spring rod extends into the side support frame to fix the sliding rod in the desired position. The injection snap-fit ​​mechanism includes a stabilizing tube and a snap-fit ​​rod. A snap-fit ​​tube is rotatably installed at the top end of the stabilizing tube. One end of the snap-fit ​​rod extends directionally into the stabilizing tube and the snap-fit ​​tube. A swivel frame is installed on the inner wall of the snap-fit ​​tube. A fixing block is fixedly installed on the outer wall of the snap-fit ​​rod, and a snap-fit ​​spring rod is installed on the fixing block. A snap-fit ​​groove is opened on the inner wall of the snap-fit ​​tube. The swivel frame pushes the snap-fit ​​spring rod into the snap-fit ​​groove and seals one end of the snap-fit ​​spring rod in the snap-fit ​​groove.

[0007] The present invention is further configured such that the snap-fit ​​auxiliary mechanism includes a friction ring and a threaded sleeve. The friction ring is installed at the bottom end of the side wall of the snap-fit ​​tube, and the threaded sleeve is threadedly connected to the outer wall of the stabilizing tube. A rubber ring is installed at the top end of the threaded sleeve. The threaded sleeve pushes the rubber ring against the bottom end of the friction ring, so that the snap-fit ​​tube is fixed on the stabilizing tube.

[0008] The present invention is further configured such that a support column is installed on the side of the bracket, and a hydraulic cylinder is installed at the top end of the support column. The support column is installed on the side of the bracket to provide vertical support for the lifting system and bear the weight of the hydraulic cylinder and the lifting frame as well as the working load.

This mechanism can stably fix containers of various specifications, ensuring that the containers do not shake or shift during injection, improving dispensing accuracy and safety, while also featuring rapid adjustment and easy operation.

[0015] This invention features an injection locking mechanism. This mechanism employs a quick-connect design of a stabilizing tube, a locking tube, and a locking rod, achieving a secure connection between the injection component and the lifting system. The locking tube is rotatably mounted on the top of the stabilizing tube, providing a flexible connection interface. An automatic locking mechanism ensures that when the locking rod is inserted, the rotating frame pushes the spring rod into the locking groove to form a reliable lock. The push-out spring, in conjunction with the inner retaining ring, provides disassembly assistance for quick separation. This mechanism enables rapid replacement and height adjustment of the injection component, is easy to operate, and provides a secure connection, improving the equipment's working efficiency and maintenance convenience.

[0016] This invention incorporates a snap-fit ​​auxiliary mechanism. This mechanism, through the cooperation of a friction ring, a threaded sleeve, and a rubber ring, provides additional stable support to the snap-fit ​​system. The threaded sleeve achieves adjustable clamping force through a threaded connection, and the rubber ring is pushed against the friction ring to generate sufficient friction, further securing the snap-fit ​​tube to the stabilizing tube. This mechanism effectively prevents loosening of the connection due to vibration or pressure changes during injection, ensuring the stability and reliability of the entire injection system, improving dispensing accuracy, and extending equipment lifespan.

[0022] Please see Figures 1-5A solvent dispenser for food testing includes a support frame 1, a transport track assembly 2, an injection assembly 3, a clamping mechanism, an injection clamping mechanism, and a clamping auxiliary mechanism. The clamping mechanism includes side supports 4 and movable clamping plates 5. The side supports 4 are symmetrically installed on both sides of the transport track assembly 2. A slide rod 6 is slidably installed on the side supports 4, and a movable clamping plate 5 is installed at one end of the slide rod 6. A pressure spring rod 7 is installed on the side supports 4, and the pressure spring rod 7 extends into the side supports 4 to fix the slide rod 6 in the desired position. The injection clamping mechanism... The structure includes a stabilizing tube 8 and a clamping rod 9. A clamping tube 10 is rotatably installed at the top end of the stabilizing tube 8. One end of the clamping rod 9 extends directionally into the stabilizing tube 8 and the clamping tube 10. A swivel frame 11 is installed on the inner wall of the clamping tube 10. A fixing block 12 is fixedly installed on the outer wall of the clamping rod 9. A snap spring rod 13 is installed on the fixing block 12. A snap groove 14 is opened on the inner wall of the clamping tube 10. The swivel frame 11 pushes the snap spring rod 13 into the snap groove 14 and seals one end of the snap spring rod 13 in the snap groove 14.

[0023] In this embodiment, the clamping mechanism uses side support frames 4 and movable clamping plates 5 to fix and clamp the container. During operation, the container is transported to the designated position by the transport track assembly 2. The operator adjusts the position of the slide rod 6 on the side support frame 4 according to the container size so that the movable clamping plate 5 can be accurately aligned with the container. After adjustment, the pressure spring rod 7 extends into the side support frame 4 to fix the slide rod 6 in the required position. When the container reaches the clamping position, the movable clamping plates 5 on both sides move towards the center simultaneously to symmetrically clamp the container, ensuring that the container remains stable during injection and preventing shaking or displacement from affecting the injection accuracy. The injection clamping mechanism uses a stabilizing tube 8 and a clamping mechanism. The tube 10 and the snap-fit ​​rod 9 enable quick connection of the injection component 3. During operation, the operator inserts one end of the snap-fit ​​rod 9 into the stabilizing tube 8 and the snap-fit ​​tube 10. When the snap-fit ​​rod 9 is inserted into place, the swivel frame 11 automatically pushes the snap-fit ​​rod 13 on the fixing block 12, so that the snap-fit ​​rod 13 extends into the snap-fit ​​groove 14 on the inner wall of the snap-fit ​​tube 10. One end of the snap-fit ​​rod 13 is sealed in the snap-fit ​​groove 14 to form a lock, ensuring that the injection component 3 is firmly connected to the lifting system. When disassembly is required, the snap-fit ​​tube 10 is rotated in the opposite direction, and the snap-fit ​​rod 13 moves away from the snap-fit ​​groove 14. The push-out spring 801 cooperates with the inner retaining ring 24 to provide a push-out force, which facilitates the snap-fit ​​rod 9 to disengage.

[0024] The snap-fit ​​auxiliary mechanism includes a friction ring 15 and a threaded sleeve 16. The friction ring 15 is installed at the bottom end of the side wall of the snap-fit ​​tube 10, and the threaded sleeve 16 is threadedly connected to the outer wall of the support tube 8. A rubber ring 17 is installed at the top end of the threaded sleeve 16. The threaded sleeve 16 pushes the rubber ring 17 against the bottom end of the friction ring 15, so that the snap-fit ​​tube 10 is fixed on the stabilizing tube 8.

[0025] In this embodiment, the snap-fit ​​auxiliary mechanism provides additional stable support through the friction ring 15, the threaded sleeve 16, and the rubber ring 17. During operation, the threaded sleeve 16 is threadedly connected to the outer wall of the stabilizing tube 8. The operator rotates the threaded sleeve 16 to move it downwards, and the rubber ring 17 at the top of the threaded sleeve 16 is pushed against the friction ring 15 installed at the bottom of the side wall of the snap-fit ​​tube 10. The tight fit between the rubber ring 17 and the friction ring 15 generates sufficient friction to further fix the snap-fit ​​tube 10 on the stabilizing tube 8, preventing loosening due to vibration or pressure changes during the injection process.

[0026] Please see Figures 1-5 As a supplementary embodiment of a solvent dispenser for food testing, comprising a clamping mechanism, an injection clamping mechanism, and a clamping auxiliary mechanism: A support column 18 is mounted on the side of the support 1, and a hydraulic cylinder 19 is mounted on the top end of the support column 18. A lifting frame 20 is longitudinally slidably mounted on the support column 18, and one end of the hydraulic cylinder 19 is connected to the lifting frame 20. The lifting frame 20 has adjustment holes 21, and multiple sets of adjustment holes 21 are provided. A contact plate 22 is mounted on the side wall of the clamping tube 10, and the contact plate 22 is connected to the lifting frame 20. The top end of the injection component 3 is in contact with the top end of the injection component 3. The top end of the injection component 3 is equipped with a connecting block 23. The connecting block 23 can be threadedly fixedly connected with the snap-fit ​​rod 9. The injection component 3 is provided with multiple sets. One end of the snap-fit ​​rod 9 can extend into the adjustment hole 21 and into the stabilizing tube 8 and the snap-fit ​​tube 10 for snap-fit. The injection component 3 is arranged opposite to the transport track component 2. An inner retaining ring 24 is installed on the inner wall of the stabilizing tube 8. An ejection spring 801 is installed on the side wall of the snap-fit ​​rod 9, and one end of the ejection spring 801 is in contact with the bottom end of the inner retaining ring 24.

[0027] More specifically, the support column 18 and hydraulic cylinder 19 system on the support frame 1 are activated, and the lifting frame 20 is driven to rise to a suitable height by the hydraulic cylinder 19. The corresponding adjustment hole 21 position is selected according to the container height. The transport track assembly 2 transports the container to be injected to the working position. The movable clamping plate 5 of the clamping mechanism is adjusted to a suitable spacing and clamps the container. Multiple injection components 3 are threadedly connected to the locking rod 9 via connecting block 23. The locking rod 9 extends into the adjustment hole 21 and engages with the injection locking mechanism to form a secure connection. The hydraulic cylinder 19 drives the lifting frame 20 to rise or fall, via the contact plate 2. 2. Contact with the top of the lifting frame 20 adjusts the entire injection system to the optimal injection height. The locking auxiliary mechanism is activated, and the threaded sleeve 16 pushes the rubber ring 17 to press the friction ring 15, ensuring the stability and fixation of the entire injection system. The injection component 3 starts working, accurately injecting the solvent into the clamped container. The injection locking mechanism ensures the stability of the injection process. After injection, the lifting frame 20 is reset, the clamping mechanism releases the container, and the transport track component 2 transports the processed container away, preparing for the next work cycle. The injection locking mechanism allows for the detachment of the injection component 3, enabling convenient maintenance or repair.

[0028] In summary, during the use or operation of the overall equipment: when the clamping mechanism is required, it uses the side support frame 4 and the movable clamping plate 5 to fix and clamp the container. During operation, the container is transported to the designated position by the transport track assembly 2. The operator adjusts the position of the slide rod 6 on the side support frame 4 according to the container size so that the movable clamping plate 5 can be accurately aligned with the container. After adjustment, the pressure spring rod 7 extends into the side support frame 4 to fix the slide rod 6 in the required position. When the container reaches the clamping position, the movable clamping plates 5 on both sides move towards the center at the same time to symmetrically clamp the container, ensuring that the container remains stable during the injection process and preventing shaking or displacement from affecting the injection accuracy.

[0029] When the injection clamping mechanism is in operation, it enables the quick connection of the injection component 3 through the stabilizing tube 8, the clamping tube 10, and the clamping rod 9. During operation, the operator inserts one end of the clamping rod 9 into the stabilizing tube 8 and the clamping tube 10. When the clamping rod 9 is inserted into place, the rotating frame 11 automatically pushes the retaining spring rod 13 on the fixing block 12, causing the retaining spring rod 13 to extend into the retaining groove 14 on the inner wall of the clamping tube 10. One end of the retaining spring rod 13 is sealed in the retaining groove 14 to form a lock, ensuring that the injection component 3 is firmly connected to the lifting system. When disassembly is required, the clamping tube 10 is rotated in the opposite direction, and the retaining spring rod 13 moves away from the retaining groove 14. The push-out spring 801 and the inner retaining ring 24 cooperate to provide a push-out force, making it easy for the clamping rod 9 to disengage.

[0030] When the snap-fit ​​auxiliary mechanism is required to operate, it provides additional stable support through the friction ring 15, threaded sleeve 16, and rubber ring 17. During operation, the threaded sleeve 16 is threadedly connected to the outer wall of the snap-fit ​​tube 10. The operator rotates the threaded sleeve 16 to move it downwards, and the rubber ring 17 at the top of the threaded sleeve 16 is pushed against the friction ring 15 installed at the bottom of the side wall of the snap-fit ​​tube 10. The tight fit between the rubber ring 17 and the friction ring 15 generates sufficient friction to further fix the snap-fit ​​tube 10 on the stabilizing tube 8, preventing loosening due to vibration or pressure changes during the injection process.

[0031] The support column 18 and hydraulic cylinder 19 system on the support frame 1 are activated. The lifting frame 20 is driven to rise to a suitable height by the hydraulic cylinder 19. The position of the corresponding adjustment hole 21 is selected according to the container height. The transport track assembly 2 transports the container to be injected to the working position. The movable clamping plate 5 of the clamping mechanism is adjusted to a suitable distance and clamps the container. Multiple injection components 3 are threadedly fixed to the locking rod 9 through the connecting block 23. The locking rod 9 extends into the adjustment hole 21 and engages with the injection locking mechanism to form a firm connection. The hydraulic cylinder 19 drives the lifting frame 20 to rise or fall, and the contact plate 22 connects with... The contact at the top of the lifting frame 20 adjusts the entire injection system to the optimal injection height. The locking auxiliary mechanism is activated, and the threaded sleeve 16 pushes the rubber ring 17 to press the friction ring 15, ensuring the stability and fixation of the entire injection system. The injection component 3 starts working, accurately injecting the solvent into the clamped container. The injection locking mechanism ensures the stability of the injection process. After injection, the lifting frame 20 resets, the clamping mechanism releases the container, and the transport track component 2 transports the processed container away, preparing for the next work cycle. The injection locking mechanism allows for the detachment of the injection component 3, enabling convenient maintenance or repair.
